To all whom it may concern:

Be it knownthat'I, JOHN SAUL, a citizen of the United States, and a residentof Jersey City, county'of Hudson, and State of New Jersey, have invented a new: and useful Improvement in Antirattlers for Windows, of which the following is a full, clear, and exact description. H

My invention relates toimprovements in anti-rattling devices for sliding windows. 7 The object of my invention is to produce a simple and efficient device which can be attached to the window'sashso as to be entirely concealed, and which will take up all the slack of the sash and prevent it from rattling, and will also facilitate its easy movement up and down in the window frame.

My invention comprises a swinging arm which is placed in a recess of the sash and which carries a roller normally pressed out by a spring so as to engage the parting strip or some other stationary part of the window frame, and the pressure of the roller will take up any slack which the sash may have in the frame, and because of the roller hearing against the stationary part of the frame, will cause the sash to move very easily and yet tightly.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar reference characters indicate corresponding parts in all the views.

Figure l is a perspective view showing my improved anti-rattling device as applied to a sash, and Fig. 2 is a broken side elevation of the sash and the adjacent parting strip with my anti-rattling device in a recess on the sash.

My invention has a bifurcated swingingv arm 10 which at one end is pivoted on a stout screw 11, and which is adapted to lie in a recess 12 in one side of the sash 13. Obviously the arm might not be bifurcated, but it is better to have it forked as shown, and I prefer to have the recess 12 generally semi-circular so that the spring 16 hereinafter referred to, will fit nicely against the curved back wall of the recess. The screw 11 is secured to the side of the sash 13, and the roller 14 is normally pressed out so as to bear against the parting strip 15, or against some corresponding stationary part of the window frame which comes opposite the sash. The spring 16 is preferably i Specification of Letters Patent.

"in the recess 12 of the sash.

understood, however, that the spring might in a corresponding recess of the arm 10.

Clhisarrangement makes it easy to apply the screw tothe arm without other fasten- 1ngs, and it also secures thespring so that Patentetlfl et. 5, rai s. Application filed'January 6, 1915. Serial No. 730.

it cannot get loose when theattachment is it: will be be of different shape, or otherwise applied, without materially affecting the invention.

In Fig. 2 it will be clearly seen how the anti-rattler works. WVhen the sash is opposite the strip 15, or some corresponding stationary part, the roller 14 is forced inward, but under the pressure of the spring 16 it bears against the stationary part of the frame, that is the strip 15, so as to take up any lost motion of the sash and prevent it from rattling, and it will be seen that the roller will ride smoothly and freely on the part against which it bears so that the sash will move very easily.

It will also be noticed that the curved spring 16 fits nicely against the back wall of the recess 12, and that its tension acting on the arm 10 serves to swing the free end of the arm outward and causes the roller 14 to bear with sufficient; tension against the part it abuts with.

It will further be noticed that the device is absolutely concealed when the sash is in position, and that it can be easily applied, also that it does not in any way interfere with any ordinary window construction.

A. further advantage of the invention is that by taking up the lost motion of the sash, it obviates the need of using weather strips, as it serves to press one side of the sash against the adjacent stationary part of the frame, and so shuts out the air and water.

Particular attention is called to the fact that the spring 16 has a compound action which gives it the necessary strength, and still distributes the pressure so that the roller 14: is acted on in a way to prevent anti-rattling, but not so hard as to cause it to dig-into the abutting surface against which it rides. Nith my spring the action is easy but sufficiently strong. /Vhen presaction is to tighten the spring 16 around sure is first applied to the roller 'igfthg the pivoted end of the arm 10, after which the pressureis distributed over the back Wall of the recess 12, and the Whole force of the spring is utilizedto swing the arm outward from the front top end of "the spring 16. 7
